Kroll continued: "Not long after the end of the nuclear war in the old era, the surviving humans discovered that there were 13 regions on the ancestral planet Earth that were not affected by nuclear radiation, and that the biosphere inside was exactly the same as it was before the nuclear war.

So, the surviving humans traveled to these 13 areas where they could live.

Among the survivors, a handful of scientists survived, and in the heart of the middle of the 13 unaffected areas, they discovered a mysterious stone, which is said to be the Life Stone!

Within a diameter of 1,000 kilometers, the Living Stone has formed a complete isolation area, and the environment in the biosphere is still the same as before the start of the nuclear war, unaffected.

And all thermal weapons, energy weapons, cannot be used in this area. In other words, in this region, cold weapons have once again become the mainstream of fighting and warfare between human beings. ”

Ye Chen's heart was directly speechless at this time, after launching a nuclear war, he had made the ancestral planet earth like that, and the human race was still fighting.

But he didn't think too much about it, and continued to listen quietly, and Kroll didn't stop, and continued:

According to the accounts of this part of the database, the greedy nature of human beings did not end with the end of nuclear war.

They can only use cold weapons in the ecosystem, but they continue to fight each other for survival resources, and the 13 ecosystems that have not been affected by the nuclear war have been engaged in a melee for 20 years.

In the past two decades, the technology of the surviving humans has also continued to develop, and finally ushered in the Age of Discovery, with the continuous development of new resource habitable planets, the ancestral planet Earth has also been abandoned by humans.

The life stones that existed in the most primitive 13 biospheres disappeared at that time, and it is said that some were taken away by various human forces, and some were left in the universe because of the struggle between forces.

The elliptical object with a diamond-shaped crystal in the middle that you found that day was one of the 13 life stones on the ancestral planet earth, which was No. 3, that is, the life stone in the No. 3 ecosystem on the ancestral planet at that time.

The name of this life stone was Kroll at that time, and the attribute of the No. 3 life stone is the ability of the biological system, the biggest of which is regeneration, or cell cloning.

You've seen the basics like devouring, and as for the rest, you don't understand it now. You just remember that the ability of Life Stone No. 3 is the ability of the biology department.

Ye Chen's head was big when he heard this, but he still patiently listened to Kroll's words:

"And I, including the two sarcomas behind you, it's called Biological Inner Armor, and I were both born from the No. 3 Life Stone, and to exert my full ability, I need the cooperation of Biological Inner Armor.

At that time, there were also mutated humans on the ancestral planet Earth due to nuclear radiation, so only the DNA in the fresh blood of pure humans could be activated.

Of course, the Life Stone will choose the host object, and not every pure human can get the approval of the Life Stone, and in this regard, you are obviously a lucky one. ”

"And what's the matter with this creature inner armor on my body?" Although Ye Chen was shocked when he heard this, he still asked calmly.

"At that time, the battle mecha born in the No. 3 Life Stone was actually two sets, one outer armor and one inner armor.

The inner armor is a close-fitting biological inner armor that has the ability to survive in a vacuum for a period of time.

My former master was able to fight in space for a period of time wearing only the Inner Armor, which of course was fully functional and bio-energetic.

Of course, this inner armor form on your body today does not have this function. The biggest ability of this set of inner armor is that it can be regenerated, or cloned, and you can now roughly understand it as the ability attribute that can grow again after the mutant gecko's tail is broken. ”

At this time, Ye Chen continued to listen confused.

"Then, the living inner armor can devour everything else it thinks is a match, and has the ability to change itself, which can also be seen as changing the ability of the human who owns it.

After fusing the Life Stone, the human also has all the abilities of the Life Stone he fused, but it needs to be developed gradually.

For example, you can't survive in space now, but you can survive most of the surface of this junk star without being affected by nuclear radiation.

If it's in the water at a depth of no more than 1,000 meters, you can also survive by breathing through this set of creature inner armor. Kroll continued.

After hearing so much, although Ye Chen roughly understood what had happened, he still had many questions, so he continued:

"Then why did I become so hungry so easily, I used to be able to eat half a month's food, but now it is only enough for me to eat one meal, what kind of problems have occurred in my body?"

"Any mecha needs to be powered by energy, I am an external mecha, and the energy consumed is normal energy, light energy, electrical energy, ore energy, all energy that can be converted into energy battery blocks can keep me running.

However, the inner armor is a biological mecha, and it must rely on biological energy to operate, and the food you eat in the garbage star is very low-level, and the energy contained in the food cannot easily maintain the operation of your personal biological mecha.

If you eat normal food for half a month at a time, you can only maintain the normal operation of this set of biological inner armor for 2 hours.

If you use this set of creature armor for more than 2 hours in a row, you will faint from hunger. If you encounter this situation in battle, you understand the consequences. Kroll replied to Ye Chen.

"So how can I use this set of creature armor normally? What kind of foods do I need to eat for bioenergy? Saying this, Ye Chen faintly felt in his heart that what Kroll was about to say was similar to what he was thinking in his heart now.

That is, in today's Age of Discovery, one of the most advanced foods for human beings, nutrient solution!

Kroll looked at Ye Chen very humanely, and said to Ye Chen: "Yes, you can't meet your body's consumption by eating ordinary mutant beast meat or compressed dry food now, even if you don't move every day and only sleep."

It turns out that you can eat half a month's food, but now you can only maintain your basic consumption for three days, and this is still when the biological inner armor has not activated more functions. ”

"So how much nutrient solution do I need each day to meet my body's consumption?" Ye Chen hurriedly asked.

"According to the current daily consumption of Inner Armor, you need to replenish at least one bottle of ninth-level nutrient solution every week to be satisfied.

If it's an eighth-level nutrient solution, you can maintain a month's daily consumption or three days of high-intensity combat consumption after drinking.

The ninth-level nutrient solution can only sustain you for three hours of high-intensity combat consumption. There is a database of specific knowledge levels of nutrient solution, which I will pass on to you now. ”

Because of the Life Stone, there has long been a connection between Kroll and Ye Chen, and Kroll can directly transmit these materials in Ye Chen's mind.

Nutrient solution is definitely one of the greatest inventions since mankind entered the Age of Discovery.

To put it bluntly, nutrient solution is a variety of beneficial liquids with different functions obtained by humans after concentrating and purifying various materials that are beneficial to the human body.

Specifically, you can refer to the help of making drugs to the human body, but the nutrient solution does not have any side effects. The production of nutrient solution also gave birth to a new profession for mankind, the pharmacist.

The nutrient solution made by the pharmacist of different levels is also divided into different grades, a total of nine grades, the highest level of the first level, the lowest level of the ninth level, and the level of the pharmacist also matches the level of the nutrient solution he can make.

Although the high-grade nutrient solution cannot resurrect the dead, it is still possible to restore the dying human being to its heyday, and even the high-grade different types of nutrient solutions can also allow humans to have other abilities.

Even the lowest grade of the ninth-level nutrient solution has the basic ability to improve the basic quality of the human body.

Of course, it's impossible to become Superman, but if you can quote it a few times, it's okay to improve your physical fitness by one or two times.

The nutrient solution is also a kind of capital for human beings to compete with other intelligent races in the universe.

In the Age of Discovery, with the continuous development of the universe by human beings, many other intelligent races of the universe have also been discovered, so human beings are not alone in the vast universe.

The history of human space development is not only a history of human beings fighting each other with the same race for various resources, but also a history of war between the human race and the extraterrestrial intelligent race.

Of course, Ye Chen had heard of the nutrient solution, and his current home was a small interstellar transport ship, and the original owner of this ship used this ship to transport the ninth-level nutrient solution.

But Ye Chen also knew that in No. 779 Junk Star, the nutrient solution was a very, very expensive thing at all.

The last time he heard about the nutrient solution was in the black market he had just left.

At that time, the black market manager happened to purchase 10 bottles of Grade 9 Nutrient Solution from a large hunting team of several hundred people on Junk Star, and it took a huge price to get it.

I heard that the large hunting team also sacrificed a lot of people for these 10 bottles of ninth-level nutrient solution, and lost a lot of good hunters. But where they got these nutrient solutions, Ye Chen didn't know.

Thinking of this, Ye Chen immediately made a decision to get the nutrient solution from the black market and look for more nutrient solutions.

But Ye Chen is not a reckless person, he deeply knows the strength of the black market managers, the black market that can stand in this vicinity for decades is not made of mud, without strong strength, it is impossible to open a black market in No. 779 Garbage Star.

Not counting the strength of the hunting team of nearly 1,000 people directly under the black market, Ye Chen knew that the black market managers must have combat mechas, and there may be more than one.

Therefore, Ye Chen will not rush to death recklessly, and must make a complete plan. Ye Chen decided to adapt to this set of creature inner armor and learn to control Kroll first, in order to make a perfect match with Kroll before making plans.

So during this time, Ye Chen still planned to hunt mutant guinea pigs, even if the mutant guinea pig meat he needed to eat was a little more. You can't rush to the black market to find nutrient solution, this kind of behavior is no different from sending you to death.
